AttributeError: '' object has no attribute 'tk' - Maryan - Oct-29-2020
I had to seperate this file from the main app, because had some errors that I had to fix them first. However, when I run the app I'm getting AttributeError. What am I missing?
from tkinter import *
from tkinter import Tk
from tkinter.ttk import Combobox
from tkcalendar import *
from tkinter import messagebox, filedialog
import sqlite3
class AddEmp():
def __init__(self):
### FRAMES ###
# Top Frame - Header
self.topFrame = Frame(self, height = 100, bg = '#333')
self.topFrame.pack(fill = X)
# Center Frame - Buttons
self.centerFrame= Frame(self, height = 750, bg = '#121212')
self.centerFrame.pack(fill = X)
# Top Frame - Data #
# Header in Top Frame
self.header_image = PhotoImage(file = 'img/add_employee.png')
self.header_lbl = Label(self.topFrame, image = self.header_image, bg = '#333')
self.header_lbl.grid(row = 0, column = 0, padx = 15, pady = 15)
self.header_introduction = Label(self.topFrame, text = 'Add Employee', fg = '#b3b3b3', bg = '#333')
self.header_introduction.grid(row = 0, column = 1)

root = Tk()
app = AddEmp()
root.title('All Fields are required')
root.geometry('440x823+700+150')
root.resizable(False, False)
root.mainloop()

Are you sure this ever worked? AppEmp is not any kind of window, but you pass it as the parent to a frame (as self).
I am not sure how you go about fixing this. Is AddEmp a frame? Is it a dialog? I am going to make it a frame.
from tkinter import *
from tkinter import Tk
class AddEmp(Frame): # Need some kind of frame or window as superclass
def __init__(self, *args, **kvargs):
super().__init__(*args, **kvargs) # Initialize superclass
self.pack(fill='both', expand=True) # Pack self in parent
# Now you can add widgets to self because self is a frame.
self.header_lbl = Label(self, text='Label 1')
self.header_lbl.grid(row = 0, column = 0, padx = 15, pady = 15)
self.header_introduction = Label(self, text = 'Label 2')
self.header_introduction.grid(row = 1, column = 0)
root = Tk()
AddEmp(root)
root.title('All Fields are required')
root.geometry('100x100')
root.mainloop()

It's dialog from the main app. On click this one popup. Altought I know the basics to create window, I have still trouble when there is class involved, like in this case. I'm not sure where the geometry should be inside the class, before the class or bottom like I did in the post.
